No, you got it mixed up. The fields are as follows
1st: The minute of the hour(0-59)
2nd: The hour of the day(0-23)
3rd: The day of the month (1-31)
4th: The month (1-12)
5th: The day of the week (Sun=0, Mon=1, ... Sat=6)
in your ex. 1 * * * * /usr/bin/... means every hour 12:01, 13:01, 14:01,
etc...
the asterisk * means every. It is a little confusing at first. To run every
ten minute would be 10,20,30,40,50 * * * * /usr/bin.
